' ovEn-sHELFi' I To all whom it may concern: v

Be itknown that I, JOHN W. COUMERILH, a citizen of the United States, residing at Mullan, in the county of Shoshone and State. of Idaho, have invented certain new and useful Improvements in Oven-Shelves, of which the following is a specification.

The present invention relates to improvements in oven shelves designed particularly J for use with domestic cooking stoves or ranges, to facilitate the cooking operations and provide a convenient means for manipulating the food while baking or cooking in the oven. By the utilization of my invention the bake pan or tray, on the shelf, containing the meat such as a roast to be cooked, may be easily swung out of the oven to give ac-' cess for basting or inspecting the meat,'and

the shelf may readily be adjusted asto altitude to secure best results from the heated portions of the oven.

combinations and arrangements of parts adjustment of the shelf as to altitude is at tained, as will behereinafter' 'set forth and claimed.

In the. accompanying drawings I have physical embodiment of my invention, the

parts being combined and arrangedaccord ing to the best mode so far devised for the practical application of the principles of my invention.

Figure 1 is a perspective View of a domestic cooking range with the oven door open, showing the shelf of the present invention installed therein, the shelf being partly swung out from the oven for convenience of illustrating it.

Fig. 2 is a top plan view of the shelf, detached. 7

Fig. 3 is a perspective view of the oscillatable supporting post or standard for the shelf, partly brokenaway to show a spring bearing pin arrangement in the upper end of the post.

Fig. 4 is a sectional view of the upper hearing ring and Fig. 5 is a sectional view of the lower bearing for the post.

The post or standard is, designed to oscilupper end'of thepost bythe springfi which spaced,- transverse openings 7 for the cotter pin S, which is passed through similar openings 9 in the post and may be slipped in predetermined position.

.late and therefore is provided withia fixed -bottom bearing'pin 4L, and an upper, spring pressed bearing'pin 5 projected beyondthe 7O is seated inthe socketed end of the post and urges the upper pin outwardly. The pin is preferably "provided with ya series 0f 7 through one of the openings 7 to holdthe pin The invention consists in certain novel i 'The two bearing p'ins of the {post have theirrespective bearing rings, as the upper ring 10 and the lowerone. 11, both in the shape of open center plates-of metal andeach provided with a number of spurs 12 tofasten in the-upper plate 12 and the lower plate I 1 13 of the oven. 'When these bearing rings are properly alined and-fastened securely in their respective oyen plates they form the supports for the oscillatable post which is pivoted by its bearing pins therein and the post may be swung or turned on its pins as desired.

The shelf 14;;is preferably of cast metal,

andv approximately rectangular in shape,

and perforated as shown to permit equal distribution of the heat, in the oven, and in order that the shelf may be adapted to fill the entire horizontalarea of the oven, and yet be free to swing into or out of the oven, I provide one end and corner of the shelf with a wing 15, pivoted'at'16 on the shelf. This wingis approximately triangular in shape,

having one'square corner to complete the rectangular outline of the shelf, and is adapted to swing under the shelf at its cut-away endi 15, being guided by the lug or flange 17 se- At'one corner of theshelf is secured the i05 cured at the under side of the shelf nearits flanged retaining thimble 18 which is of the cross area of the post with. which it ooacts to support the shelf; The thimble is attached atithe upper side of the shelf, in

one corner and-the shelf is provided with a .registered opening for the thiinble.

Itwill be noted that the socket has paral lel side walls and parallel end walls, but the a endwalls are inclined to the perpendicular,

the angle of inclination being-the same as that of the undercut face 3 of the postabove its shoulder 2, and when the shelf is being supported on the post, the edge of the -thiinble rests snugly in the space above and on the shoulder of the post, withthe incl ned faces in close contact andthe shoulder supporting the load.

' it will readily be seen that the shelf,

1 load on the shoulder and the shelf falls to through its thimble, may readily he slipped over the end of the post, before it is placed "in the oven, while the shelf is slightly tipped cup at its wlng-end, and while held in this position relativewto the post, maybe dropped to the desired shoulder and then when the support of thewinged end of the shelf is released, the weight of the shelf imposes the a horizontal, supported position. After the lower fixed pin has been entered in its bearing socket, the pin 5 may be retracted and so held by acotter S, and the post alined with the two bearing'rings. Y Then the cotter is withdrawn and the spring 6 pushes the upper pin intoits bearing socket and'the 'post 18 now in operat veposltion. The cottermay be passed through the holes 9 in the post and the alined or regis'teringopening'? in the upperpin to make a p'ositiveattachment of the upper pin'with its post.

, Itwill readily be apparent-that the shelf may be swung into and out from the oven in horizontal 'alane and the Win of the shelf l I 1 u b I 0 permits it to swing onlts pivot, and likewise forms a part of the supporting shelf when i in I the oven.

What I claim is v .7

T he combination with an oven having upper and lower plates, of apost fashioned on 1 one'side' with spaced shoulders and inclined faces, a non-rotatable shelf on the post formed with a supporting thimble adapted v to co-act with the inclined faces on the post and rest on a shoulder, allned bearing rings secured in said plates, bearing pins on the post operative in said rings, and one of said pins having spring connection with the'post for the purpose specified.

In testimony whereof I afix my signature.
